No account needed and nothing is saved. Returns the positions, a short summary and readingUrl, a link that opens the free written reading on celestio.ai with the details filled in.

compare_birth_charts | Compatibility between two people (partners, crushes, friends, family) from their names, birth dates, places and, if known, times. No account needed and nothing is saved. Returns the strongest connections between the two charts and compatibilityUrl, a link that opens the free compatibility preview on celestio.ai with both people filled in. params: first*, second*, relationship |
get_birth_reading | Writes (or returns the already written) free personal birth chart reading for someone, saved in the connected Celestio account.
